What’s causing my blocked nose at night?

There’s nothing worse than settling down for a good night’s sleep only to discover that a blocked nose is affecting your breathing. So why can a blocked nose suddenly appear or get worse at night? Today I’m discussing how allergies, dusty air, pregnancy and infection can affect your blocked nose, and why it can get worse at night.

What causes a blocked nose?

The most common cause of a blocked nose is an infection like a cold or flu. This can cause the nasal passages to become inflamed, or could cause an excess production of mucus in order to flush out pathogens. All this inflammation and excess mucus can make it hard for the nose to keep itself well-drained, resulting in that blocked feeling!

However, you might find that your blocked nose gets worse at night, or that it is actually runny during the day but becomes blocked as soon as you go to bed – why is this?

Why does my blocked nose get worse at night?

In many cases it is the simple act of lying down that causes a blocked nose, rather than the time of day. When you lie down in bed, your body is no longer able to drain mucus out of your nose through your throat, because gravity isn’t working in the right direction anymore.

This could mean that if you’re suffering from a blocked nose it will get worse at night when you lie down. If you’re suffering from a runny nose, you may notice that this becomes blocked when you go to bed as it is not able to drain as it has been doing (rather annoyingly!) during the day. You may even find that your nose feels completely normal all day and suddenly becomes blocked for no reason at night – this is because a slight increase in mucus production might not be noticeable during the day as the nose keeps itself drained and clear, but it will certainly become noticeable when this draining function is removed.

What else could be causing it?

However, there are other causes of a blocked nose. So, what are these and why can they make your blocked nose worse at night?

First and foremost, it is vital that the allergens which affect you are identified and removed from the bedroom, the home and the surrounding area. If pollen is a trigger, shut your bedroom windows at night. A shower or bath at night may also help to remove any pollen which has accumulated on the body during the day. You could also try our Luffa Nasal Spray which works to rinse and clean the nasal passages of any hayfever causing allergens.

If cigarette smoke is the issue, ban this around the home, even for guests! Should an animal be the trigger, contact should be minimised, and pets should be kept away from bedrooms.

Dust mites are a common allergen and often forgotten as a cause of a blocked nose at night. It is important that bed covers and sheets are washed regularly and that a dust mite protector is used on the mattress.

2. Sinusitus

Sinuses are are air-filled cavities in your face. We do not fully understand why they exist, but one possible reason is so that our voices are more resonant and louder. Sinusitis is inflammation of these cavities – this may arise as a temporary symptom of a cold or flu, or become more prolonged or chronic.

Inflammation in the sinuses leads to an increase in the amount of mucus secreted, and as this collects in the upper nasal passages, a blocked nose results. Symptoms can be worse at night, and be affected by posture or your sleeping position.

What you can do

A normal bout of sinusitus should only last a week and clear on its own without any assistance from a GP or the need for antibotics. Over-the-counter decongestants, taken orally, can be helpful but remember that many contain caffeine or other stimulants which may keep you awake and hence, should not be taken near bedtime.

Home remedies may also offer some help to those with a blocked nose. Breathing in the steam from a hot shower helps by liquefying mucus and unblocking nasal passages. Similarly many people find it useful to use a bowl of steaming water, placing their head over the bowl with a towel covering, and inhaling slowly and deeply. A few drops of a menthol or eucalyptus oil added to the hot water can improve the decongestant action.

A salt water solution can help to liquefy mucus. Put ½ teaspoon of salt into the equivalent of two mugs of water and gently sniff the liquid into your nostrils.

As with so many other ailments, drinking plenty of fluid is also beneficial. This helps to keep mucus thin and reduce the swelling in your sinuses.

Avoid alcohol – this relaxes (dilates) your blood vessels and increase swelling of tissues in your upper nasal passages, which is something you don’t want if you have a blocked nose.

3. Dry dusty air

Air containing little or no moisture can be a cause of a blocked nose especially at night. As your nasal passages become increasingly dry, nasal tissues over-produce mucus in compensation, in an effort to keep itself moist. This overproduction leads to a blocked nose.

What you can do

Dry or dusty air is not a particular problem for those of us who live in the UK, but could be an issue if you spend a lot of time in an air-conditioned environment or in other countries, particularly in those with desert or arid lands. Humidifiers can be extremely helpful as they add moisture to the air, which in turn allows symptoms to become more manageable.

4. Physical obstruction

Here, we are not talking about a pea up a child’s nose. There are two main physical causes for a blocked nose and both can be worse at night:

Nasal polyps – these are small growths of extra tissue in the nasal passages. They arise as a result of chronic inflammation such as with allergic rhinitis or sinusitis.

Deviated septum – this basically means that the bones in the nose are not in the right place. It may arise as a congenital malformation or injury (typically a rugby injury), leading to blockage of the nasal passages.

What you can do

In principle, the long-term ‘cure’ for these two types of physical obstruction is surgery. In some people, nasal decongestants can help alleviate symptoms. Another option is using nasal strips which allow the passageways to open slightly, assisting with breathing.

5. Pregnancy

During this stage in a woman’s life, levels of oestrogen and progesterone rise. One result is an increase in blood flow to many parts of the body. In the nasal passages, the delicate tissues are more prone to swelling, leading to restriction of air flow and a blocked nose. Posture can worsen the situation which is why symptoms can be worse at night. If you suffer from asthma, a blocked nose during pregnancy will be something extra to cope with.

What you can do

As with any health condition that occurs during pregnancy, use of any over-the-counter remedies is not recommended without first consulting a midwife or GP.

Home remedies such as steaming the nasal passageways may of course be used.

In addition, avoid any potential allergens as much as possible and drink plenty of fluids.

Other useful ideas include elevating your head while sleeping by putting your pillow at a slight angle, and using saline drops in order to keep your nasal passageways moist. This will also help to remove any mucus which may be stored.

6. Children and blocked noses

The main cause of blocked noses in children are viral infections. Children are much more likely to pick up bugs as their immune systems are still developing and consequently, resistance to infection is low. In addition, a child’s nasal passageways are narrow and easily obstructed, so any swelling of the nasal tissues makes a blocked nose more likely.

What you can do

Place a few drops of menthol based essential oils on the front of clothing at the top of the chest just under the neck. The vapours released will be inhaled and this will help to relieve congestion.

Sleep will be disturbed in many children with a blocked nose and keeping the bedroom humid will help. One easy way of doing this is to place bowls of steaming hot water around the child at bedtime. Again, a few drops of menthol based oils will help.

Steam from a hot bath or shower will also do the same trick in relieving symptoms during the day or before bed.

Build up your child’s immune system using Echinacea. In the UK and Ireland, use of this herb for children under 12 is not recommended by the Medicines authority. However, countries such as Switzerland allow for use of Echinacea in children from the age of 4 onwards.

Lastly but most importantly, should you have any concerns relating to your child’s health, contact your GP.

Hi Jen:
I just read and very impressed with your article about mentioning of nose blockage in detail. I am suffering with nose blockage for a long time. Now I will follow your article and try to find out the causes of my nose blockage. Thanks you very much for these detail causes.

Hello
Getting a runny nose in only one location may indicate that there is something either in the environment or in the atmosphere that you are allergic to such as dust, heat, lack of ventilation etc, maybe have a look round the room to see if this is the case. You may find having some water to drink can help or you could try the Pollinosan Nasal Spray for allergies.

Hi Jen, what a masterpiece.This is the first time I am getting a detailed explanation about blocked nose.
My son will be 4 years old by the end of December and for the most part of his life, I can count on my fingertips the nights he had slept all through without waking up because of his blocked nose. When he has afternoon sleep, no matter how long he sleeps, there will be no issues. Different story at night, starts snoring immediately he hits the pillow, nose instantly wet and runny, inflamed ,sinuses that completely blocks his nostrils !This happens daily and ONLY at night ! GP started with nasal drops and has now been prescribing different kinds of of inhalers all to no avail. Told her to refer the boy to hospital but she keeps saying to keep trying , for almost 4years now.I have used dehumidifier, will try dust and mite bed and pillow protectors but from what you wrote, I think my son has this nasal polyps. Please help. Thanks.

Hello, I am glad that the article has provided some useful information. If you feel the treatment is not very effective and that your son has some kind of nasal obstruction, caused by inflammation, polyps or a deviated septum for example, then an ENT specialist might indeed be the best option. It is best to go back to your GP to help move this forward for you. In the meantime, if you wish to try a natural alternative, look at Sinuforce nasal spray.

Here’s what I recommend

Did you know?

Pregnancy can make you more susceptible to a blocked nose. Hormonal changes can cause the delicate tissues of your nose to become inflamed, restricting the flow of air and causing you to experience a blocked nose.
